ANSWER:
1) Loaded-Up Fund = $ 108.15
Economy Fund = $ 107.65
2) Loaded-Up Fund = $187.16
Economy Fund = $207.79
3) 1.2953years = 15.54months, approximately 16months
Step-by-step explanation:
Labelling of values;
Loaded-Up Fund 12b-1 fee (b1) = 1%
Loaded-Up Fund front end load (f1) = 0%
Loaded-Up Fund expense ratio (e1) = 0.85%
Economy Fund 12b-1 fee (b2) = 0%
Economy Fund front end load (f2) = 2%
Economy Fund expense ratio (e2) = 0.15%
Loaded-Up Fund returns is also the Economy Fund returns = r1 = r2 = 10%
Therefore;
Returns from a fund = (1 - f) × (1 + (r - b - e))^n............(1)
Where;
Investment final value = Investment amount × (1 + return from the fund)
Therefore, equation becomes:
Investment amount × (1 - f) × (1 + (r - b - e))^n............(2)
(1)
Using equation 2
Investment amount = $100
Number of years = n = 1
Substitute the given values for
LOADED-UP FUND:
Investment final value = $100 × (1 - 0%) ×(1 + (10% - 0.1% - 0.85%))^1
= $108.15
ECONOMY FUND:
Investment final value = $100 × (1 - 2%) × (1 + (10% - 0% - 0.15%))^1
= $107.65
Therefore the investment of $100 in one year will become;
Loaded-Up Fund = $ 108.15
Economy Fund = $ 107.65
(2)
Using equation 2
Investment amount = $100
Number of years (n) = 8
Substitute the given values for
LOADED-UP FUND:
Investment final value = $100 × (1 - 0%) ×(1 + (10% - 0.1% - 0.85%))^8
= $187.16
ECONOMY FUND:
Investment final value = $100 × (1 - 2%) × (1 + (10% - 0% - 0.15%))^8
= $207.79
Therefore the investment of $100 in 8 years will become;
Loaded-Up Fund = $187.16
Economy Fund = $207.79
(3)
To find n, we equate loaded-up fund with economy fund.
Therefore;
$100 × (1 - 0%) ×(1 + (10% - 0.1% - 0.85%))^n = 100 × (1 - 2%) × (1 + (10% - 0% - 0.15%))^n
Solving out gives;
100 × (1.0815)^n = 98 × (1.0985)^n
Cross multiplying gives;
100/98 = (1.0985/1.0815)^n
Taking the natural log of both side;
n × ln(1.0985/1.0815) = ln(100/98)
Therefore
n(0.015597) = 0.020203
n = 0.020203 ÷ 0.015597 = 1.295324
n = 1.3 years
To check n in months, 1.295324 × 12 = 15.59 which will be approximately 16months
